Homework answers / question archive / Which of the following is NOT a role of histidine in hemoglobin? Why is hemoglobin's affinity for oxygen sensitive to small changes in pH (the Bohr effect)? If hemoglobin is in the 'T' state, what is the first component of the peptide chain that moves in response to oxygen binding? If hemoglobin is in the T state, what happens at one -subunit when the other -subunit binds oxygen? One of the adaptations to high altitude is an increase in the concentration of BPG in red blood cells
